SMOKE PUMP.

`Application filed April 17, 1925. Serial No. 23,864.

To (/,ZZ coo/1n t may concern.'

Be it known that I, VrrTonroOnreoiA, a subject of the Kingot Italy, resident ot San Remo, Italy, have invented certain new and useful Improvements in Smoke Pumps, of which the following' is a specification.

The present invention relates to smoke pumps as are generally used in connection with honey bees` when the bees are approached for servie-e.

The invention provides tor an apparatus simple in construction and etlicient in working' and capable o't being` operated by swinginn` up and down the hand holding' it, as if it were a pistol.

A 't'urther object ot the invention is to provide for eiiicient removable means for a j continuous prmiuction oit smoke.

The nature of my invention will be made clear by the speciiication and annexed drawinp; in which j Fig. 1 is a sectional view of the improvel pump. f

Fig. 2 is a plan view of the same` Fig. 3 is a cross section on the line e-B of Fig. l.

The apparatus comprises a cylindrical metallic body 1- provided at the back end with bellows -2- of the usual cylindrical construction` working` between the wood partitions -3-4-- A further partition -5 is provided at the back portion of the body -1-, formingwith partition 4tan air chamber -G-.f while holes 7-, in said -partition `5h, are arranged in front of nozzles i on the partition 4- which provide a communication between the interior ot the bellows and the chamber `6-.

The cylindrical wall of the chambe!n 6- is provided with holes W9- to feed 'the bellows with air, from the atmosphere.

A receptacle or basket -10*, made of wire netting, provides a vwell ventilated furnace, where any smokeproducingesubstance is combusted. Y

Said basket is lodged within the body -1- and fitted between the cylindrical wall thereof, leaving a convenient space -11 tor the draft. The forward end of the basket -10. is connected through a chain -12- to a projection -l3 depending from a funnel-like cover -14- pivoted at l5- and provided with a vlock spring- -16-, adapted to engage the ange *17* 55 on the body *1 when the apparatus is in operation.

By opening the cover 14,f, the basket will be drawn out and permit a rapid inspection oi the burning' substances or the 60 easy removal or change oit the same.

For handling the apparatus, a lgrip -18- with two arms `19-20- is provided. The ends ot said arms are respectively linked or articulated to projections -21-22-,.de 65 pending'` from the cylindrical body l)v and the back partition -3 oit' the bellows, the latter being movable for the action ofthe bellows.

The operation is as t'ollowsrj The operator holds the apparatus with one hand applied either to the grip 18- l or' to the arm hl 9- and while the smoke is produced within the body -1- and the f cover 14- is shut up` the hand is swunfr 7" up and down. The swinging' movement of the hand, will cause. by inertiaand gravity,

the operation of the bellows and air jets merge from the nozzles --8` pass through the holes -TH and drive the smoke out, 8i through the tube 23- For convenience of operation the Said tubepiece 23- is made adjustable about the axis ot the apparatus. j

Having; now particularly described the nature otiny invention and the manner in which the same should be performed I claim: l

A smoke pump comprising a cylindrical body with cylindrical. bellows connected to 9 its rear end. partitions in said body'T forminp; an air chamber, nozzles projectinrf'i'rom one of said partitions and leading' air from said bellows,l holes in the cylindrical wall ot said air chamber. holes in the second parF "5 tition in alignment Vwith said-nozzles. a basket made o't' wire netting` and iitted within said body, a innnellike cover pivoted to the body` a. chain linking said basket to the cover, a double arm `grip, with two. arms im) each ot which is articulated to depending projections from said bodv and sai d bellows.

In testimony whereof I have affixed my signature.
